MIXING MECHANISM.

Specification of Letters Patent.

Patented Oct. 5, 1909.

Application filed .April 28, 1908. Serial No. 429,696.

To all whom it may concern.'

Be it known that I, SANNER E. RAY, a citizen of the United States,residing at McConnellsburg, in the county oit Fulton and State otPennsylvania, have invented a new and useful Mixing Mechanism, of whichthe t'ollowing is a specification.

The present invention while relating more particularly to mechanism forkneading dough, is unquestionably useful for mixing, stirring orchurning material, particularly that employed tor household or culinarypurposes.

The primary object of the invention is to provide a simple and novelstructure which can be cheaply constructed, and in which all materialwill be acted upon, the structure moreover being such that it can bereadilyY dismembered for the purpose of cleansing.

rlhe preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a top plan view of the same.Fig. 2 is a vertical longitudinal sectional view therethrough. Fig. 3 isa cross sectional view.

Similar reference numerals designate corresponding` parts in all thetigures ot the drawings.

In the embodiment illustrated, a receptacle is provided comprising endwalls 4, side walls 5, and a curved bottom 6, an outer casing 7 beingemployed for the bottom in order to properly support the saidreceptacle. The end walls are provided with journal bearings 8 and 9,the bearing 8 having a socket l0 that extends but partiallytherethrough, while the bearing 9 has an opening 12 entirely through it.

Rotatable stirrer mechanism is employed which includes oppositelyextending arms 18 connected by a spiral stirrer blade 14, the

arms and blades being preferably formed of a single rod or bar of metal.One of the arms 13 has an integral outstanding gudgeon 15, which isdet-achably journaled in the socket 10 of the bearing 8 while the otherarm is provided with a hub 1G having a threaded opening 17 therethrough.A handle crank 18, provided with a hand grip 19, has a gudgeon 2O thatdetachably passes through the opening 12 in the bearing 9, said gudgeonbeing provided with a threaded. terminal that screws into the opening17.

It will be evident, particularly by reterence to Fig. 2 that the arms 13are disposed in angular relation to the end walls t and thus while saidarms rotate adjacent to the end walls, there is considerable spacebetween the same and particularly in the corners formed by the bottomand the end walls not reached by the revolving arms. ln order that thematerial in such space may be properly stirred and mixed with the mainbody of the material placed in the receptacle, curved stirring fingers21 are employed that are carried by the blade 14, and have their freeends operating directly adj acent to the curved bottom and in the spacesformed between the paths of movement of the arms 13 and the end walls.Other oppositely extending and oppositely curved stirring lingers 9.2are provided that are carried by the blade let and have overlappingpaths o; movement in the central portion of the receptacle, theselingers also operating directly adjacent to the bottom G.

`With this construction, the dough or other material placed in thereceptacle, will be thoroughly stirred and kneaded when the handle crankis rotated. It will be noted that the lingers 22 continuously move thematerial toward the center so that it is fully acted upon by the bladelet, while the fingers 21, operating in the corners, carry the materialout of the same, and thus prevent dry tlour or other substance lodgingtherein. As a result, experience has demonstrated that with thismechanism, dough or other material can be thoroughly and evenly kneadedor mixed in a comparatively short time. lt will be evident that thestructure can be readily and cheaply produced, and moreover it can beeasily cleansed, tor if the stirring mechanism is held against movementand the handle crank rotated in a reverse direction to that in which itis rotated when being operated to stir the contents, the gudgeon of saidhandle crank will be unscrewed from the hub 16, whereupon the stirringmechanism can be removed.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention, will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction, may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention. orinstance while the structure disclosed 1s par- Cil ticularly intendedfor kneading dough, it will be understood that it can be employed formany analogous purposes, both for mixing and even churning.

Having thus fully described my invention, what l claim as new, anddesire to secure by Letters Patent, is

1. In mixing mechanism of the character set forth, the combination witha receptacle, of a rotary substantially spiral stiriei blade located andextending longitudinally therein, and stirring lingers carried byopposite portions of the blade, said stirring fingers extending towaideach other and having free ends that revolve in overlapping paths ofmovement.

2. ln mixing mechanism of the character forth, the combination with areceptacle, of a rotary substantially spiral stirrer blade locatedtherein, and curved stirring lingers cari'ied by opposite portions ofthe blade, said fingers extending toward each other and having free endsthat revolve in overlapping paths of movement adjacent to the walls ot'the receptacle.

3. n mixing mechanism of the character set forth, the combination with areceptacle having end walls and a bottom, of rotatable stirringmechanism located in the receptacle and including outstanding armsdisposed adjacent but in angular relation to the end walls, a bladeconnecting the arms, and stir'- ring lingers carried by the stirringmechanism and having their free ends operating in a path between thearms and the end walls.

t.. In mixing mechanism of the character set forth, the combination witha receptacle having end walls and a curved bottom, of rotatable stirringmechanism located therein and including oppositely disposed outstandingarms arranged adjacent but in angular relation to the end walls, aspiral stirring blade connecting the arms, and stirring lingers carriedby the blade and having their free ends operating in the space betweenthe end walls and the paths of movement of the arms. i

5. ln mixing mechanism ot the character set forth, the combination witha receptacle having end walls and a curved bottom, of stirring mechanismlocated in the receptacle f and comprising oppositely extending armsdisposed adjacent but in spaced relation to the end walls, a spiralstirring blade connecting the arms, curved oppositely extending stirringfingers carried by the blade and having free ends that operate adjacentto the curved bottom and in overlapping paths of movement, and othercurved stirring lingers carried by the blade and having their free endsoperating adjacent to the curved bottom and between the end walls andthe paths of movement of 'the arms.

G. In mixing mechanism ot the character described, the combination witha receptacle having end walls and a bottom, of rotatable stirringmechanism located therein and including oppositely directed outstandingarms arranged adj acent but in angular relation to the end walls, aspiral stirring blade connecting the arms, and opposite stirring lingerscarried by opposite portions of the bla-de, said stirring fingers eachextending toward the opposite end wall of the receptacle but outwardfrom the stirring blade, the tree ends of the lingers having overlappingpaths of movements.

7. n a stirring mechanism ot the class described, a receptacle havingend walls, side walls and a curved bottom, and a rotatable stirrermounted en the receptacle and cornprising oppositely extending armsadjacent to the end walls, a spiral blade connecting the arms, fingersprojecting from opposite portions of the blade and each extending towardthe opposite end walls of the receptacle, and opposed fingers projectingfrom the blade, each extending toward the adjacent end wall ot thereceptacle.

In testimony, that I claim the foregoing as my own, l have heretoatlixed my signature in lthe presence oit two witnesses.
